The specific embodiment
With reference to Fig. 1 and 2, the seat-assembly that is used for power actuated vehicle totally marks with 10.In the embodiment shown, seat-assembly 10 is used for the second series or the passenger row of vehicle.Yet, it being understood that seat-assembly 10 can be used on any seating position in the vehicle, this does not depart from scope of the present invention.Seat-assembly 10 comprises the seat cushion 12 that is used for seat occupant is supported on 14 tops, floor of vehicle.Seat-assembly 10 also comprises back of seat 16, and back of seat 16 is connecting with seat cushion 12 in the operation also and can move at as shown in Figure 1 cardinal principle vertical position and covering between the forwardly folded flat position on the seat cushion 12 as shown in Figure 2.Adjusting angle mechanism 18 is set to be used to make back of seat 16 pivoting action between vertical position and fold flat position as known in the art.Adjusting angle mechanism 18 also can provide the inclination angle adjustment of back of seat 16 with respect to seat cushion 12 front and back pivot, and thinks that the occupant provides traveling comfort.Seat-assembly 1 can move between as shown in Figure 1 seating position and stowed position as shown in Figure 2, wherein at seating position, back of seat 16 is in vertical position and seat cushion and separates above the floor 14 of vehicle and with the floor of vehicle, in the stowed position, back of seat 16 turns to fold flat position and seat cushion 12 leans against on the floor 14 with lying low.
With reference to Fig. 3 to 6, seat cushion 12 comprises chair dish 20, and described chair dish has relative top contour surface 22 and bottom profile surface 24 and extends between front end 26 and rear end 28.The respective profile that the bottom surface 24 of chair dish 20 is configured as with the floor 14 of vehicle is complementary, make seat cushion 12 when seat-assembly 10 is in the stowed position evenly against the floor 14.Front support rod 30 firmly be fixed on the bottom surface 24 and and the front end 26 adjacent places of chair dish 20 be in horizontal expansion between the opposite side of seat cushion 12.Back support rod 32 equally firmly is fixed on the bottom surface 24 and is in horizontal expansion between the opposite side of seat cushion 12 in the place adjacent with the rear end 28 of chair dish 20.A pair of seat support link 34 is used for can the pivot mode supporting and guide seat cushion 12 can the pivot mode being connected between front support rod 30 and the floor 14.More specifically, each seat support link 34 and the end 38 of front support rod 30 with can pivot mode bonded assembly first end 36 and and vehicle floor 14 extend between the mode bonded assembly second opposed end 40 pivoting.
Back of seat 16 comprises backrest frame 42, and described backrest frame extends between upper end 44 and lower end 46.Recliner brackets 48 is extended from each side of backrest frame 42 at the place, place adjacent with the lower end 46 of backrest frame 42.Support bracket 50 is used for the mode support seat back 16 that can pivot can the pivot mode to connect each recliner brackets 48 and each Support bracket 50 firmly is fixed on the floor 14.More specifically, each Support bracket 50 roughly be U-shaped and comprise outside 52 and to bias internal and with outside 52 parallel inside 54.Each adjusting angle mechanism 18 all comprises angle modulation axle 56, and this is can the pivot mode to connect the outside 52 of recliner brackets 48 and Support bracket 50, back of seat 16 is provided at the pivoting action between vertical position and the fold flat position.
With reference to Fig. 4 to 6, seat-assembly 10 comprises the fold flat mechanism that overall usefulness 58 marks.Fold flat mechanism 58 the operation on be connected between seat cushion 12 and the back of seat 16 so that seat-assembly 10 in response to back of seat 16 between vertical position and fold flat position pivoting action and between seating position and stowed position automatically the motion.Fold flat mechanism 58 comprises leg-of-mutton transmission connecting rod 60, and described transmission connecting rod 60 has first pivot 62, second pivot 64 and the 3rd pivot 66 that limits transmission connecting rod 60 each angles.First pivot 62 will transmit connecting rod 60 can the pivot mode to be connected to the inside 54 of Support bracket 50.Seat cushion link 68 and the end 72 of back support rod 32 with can pivot mode bonded assembly first end 70 and and second pivot 64 that transmits connecting rod 60 extend between the mode bonded assembly second opposed end 74 pivoting.Seat back link 76 pivot 80 places and recliner brackets 48 with can pivot mode bonded assembly first end 78 and and the 3rd pivot 66 that transmits connecting rod 60 extend between the mode bonded assembly second opposed end 82 pivoting.In the embodiment shown, when seat-assembly 10 was in seating position, first end 78 of seat back link 76 and the pivot 80 between the recliner brackets 48 were positioned at the place ahead of angle modulation axle 56 and separate with angle modulation axle 56.The 3rd pivot 66 of transmission connecting rod 60 is positioned at the below of second pivot 64 that transmits connecting rod 60 and separates with second pivot 64.It will be appreciated that though a fold flat mechanism only has been described in detail in detail, the transverse side of seat cushion 12 and back of seat 16 can both be connected by fold flat mechanism 58 in operation.
During operation, be in seating position from seat-assembly 10, seat cushion 12 separates by the top on seat support link 34 and seat cushion link 68 support vehicle floors 14 and with the floor 14 of vehicle, as shown in figs. 1 and 3.Back of seat 16 is supported on vertical position by recliner brackets 48 and seat back link 76.In order to make seat-assembly 10 move to the stowed position from seating position, adjusting angle mechanism 18 by any device well known in the art discharge with unlock and allow back of seat 16 around angle modulation axle 56 to the previous dynasty fold flat position shown in Fig. 2 and 7 pivot.In response to the pivoting action of back of seat 16, fold flat mechanism 58 forward and downwards 14 moves seat cushion 12 towards the floor automatically.More specifically, when back of seat 16 rotated forward, seat back link 76 promoted downwards to transmit connecting rod 60 through the 3rd pivot 66, thereby forced transmission connecting rod 60 to pivot with mode bonded assembly first pivot 62 that can pivot around the inside 54 with Support bracket 50.Transmit connecting rod 60 and be sent to second pivot 64, thereby make floor 14 motions of seat cushion 12 to the vehicle previous dynasty to promote seat cushion link 68 forward and downwards around the pivoting action of first pivot 62.Simultaneously, seat support link 34 pivots with mobile seat cushion 12 around second end 40, and therefore moves down seat-assembly 10 forward.Back of seat 16 continues to pivot forwardly to the fold flat position that covers seat cushion 12, and the floor 14 and the seat-assembly 10 that are close to vehicle up to seat cushion 12 shown in Fig. 2 and 7 are in the stowed position with lying low.
In order to make seat-assembly 10 be returned to seating position, back of seat 16 is upwards pivoted from fold flat position leave seat cushion 12 to vertical position.In response to the pivoting action of back of seat 16, fold flat mechanism 58 automatically with seat cushion 12 from the floor 14 upwards and remove backward.More specifically, when back of seat 16 upwards pivoted, seat back link 76 upwards spurred through the 3rd pivot 66 and transmits connecting rod 60, thereby forces transmission connecting rod 60 oppositely to pivot around first pivot 62.The pivoting action that transmits connecting rod 60 upwards spurs seat cushion link 68 so that seat cushion 12 is risen from the floor 14 of vehicle through second pivot 64 simultaneously.Simultaneously, seat support link 34 pivots so that seat cushion 12 14 is removed from the floor upwards and backward around second end 40.Back of seat 16 continues upwards to be pivoted to vertical position, be positioned at up to seat cushion 12 vehicle floor 14 the top and separate with floor 14 and seat-assembly 10 is returned to as shown in figs. 1 and 6 seating position.
The present invention will be described in the mode of example at this, it will be appreciated that employed term essence is word and description, rather than restrictive.Can make multiple remodeling and modification to the present invention according to above instruction.Therefore it being understood that within the scope of the appended claims, can outside the scope that this specification sheets is enumerated especially, put into practice the present invention.
